1Computed tomography-guided percutaneous core needle biopsy in pancreatic tumor diagnosis显示文摘AIM: To evaluate the techniques, results, and complications related to computed tomography(CT)-guided percutaneous core needle biopsies of solid pancreatic lesions.METHODS: CT-guided percutaneous biopsies of solid pancreatic lesions performed at a cancer reference center between January 2012 and September 2013 were retrospectively analyzed. Biopsy material was collected with a 16-20 G Tru-Core needle(10-15 cm; Angiotech, Vancouver, CA) using a coaxial system and automatic biopsy gun. When direct access to the lesion was not possible, indirect(transgastric or transhepatic) access or hydrodissection and/or pneumodissection maneuvers were used. Characteristics of the patients, lesions, procedures, and histologic results were recorded using a standardized form. RESULTS: A total of 103 procedures included in the study were performed on patients with a mean age of 64.8 year(range: 39-94 year). The mean size of the pancreatic lesions was 45.5 mm(range: 15-195 mm). Most(75/103, 72.8%) procedures were performed via direct access, though hydrodissection and/or pneumodissection were used in 22.2%(23/103) of cases and indirect transhepatic or transgastric access was used in 4.8%(5/103) of cases. Histologic analysis was performed on all biopsies, and diagnoses were conclusive in 98.1%(101/103) of cases, confirming3.9%(4/103) of tumors were benign and 94.2%(97/103) were malignant; results were atypical in 1.9%(2/103) of cases, requiring a repeat biopsy to diagnose a neuroendocrine tumor, and surgical resection to confirm a primary adenocarcinoma. Only mild/moderate complications were observed in 9/103 patients(8.7%),and they were more commonly associated with biopsies of lesions located in the head/uncinate process(n =8), than of those located in the body/tail(n = 1) of the pancreas, but this difference was not significant.CONCLUSION: CT-guided biopsy of a pancreatic lesion is a safe procedure with a high success rate, and is an excellent option for minimally invasive diagnosis.Chiang J Tyng Maria Fernanda A Almeida Paula NV Barbosa Almir GV Bitencourt José Augusto AG Berg Macello S Maciel Felipe JF Coimbra Luiz Henrique O Schiavon Maria Dirlei Begnami Marcos D Guimares Charles E Zurstrassen Rubens Chojniak 2015World Journal of Gastroenterology2015,21,12:14

3Ivabradine in the treatment of systolic heart failure- A systematic review and meta-analysis显示文摘AIM To perform a systematic-review and meta-analysis to compare outcomes of ivabradine combined with betablocker to beta-blocker alone in heart failure with reduced ejection fraction(HFr EF).METHODS We searched PubM ed, Cochrane, EMBASE, CINAHL and Web of Science for trials comparing ivabradine + betablocker to beta-blocker alone in HFr EF. We performed a systematic-review and meta-analysis of published literature. Primary end-point was combined end point of cardiac death and hospitalization for heart failure.RESULTS Six studies with 17671 patients were included. Mean follow-up was 8.7 ± 7.9 mo. Combined end-point of heart failure readmission and cardiovascular death was better in ivabradine + beta-blocker group compared to beta-blocker alone(RR: 0.93, 95%CI: 0.79-1.09, P = 0.354). Mean difference(MD) in heart rate was higher in the ivabradine + beta-blocker group(MD: 6.14, 95%CI: 3.80-8.48, P < 0.001). There was no difference in all cause mortality(RR: 0.98, 95%CI: 0.89-1.07, P = 0.609), cardiovascular mortality(RR: 0.99, 95%CI: 0.86-1.15, P = 0.908) or heart failure hospitalization(RR: 0.87, 95%CI: 0.68-1.11, P = 0.271). CONCLUSION From the available clinical trials, ivabradine + betablocker resulted in a significantly greater reduction in HRcoupled with improvement in combined end-point of heart failure readmission and cardiovascular death but with no improvement in all cause or cardiovascular mortality. Given the limited evidence, further randomized controlled trials are essential before widespread clinical application of ivabradine + beta-blocker is advocated for HFrEF.Mahesh Anantha Narayanan Yogesh NV Reddy Janani Baskaran Abhishek Deshmukh David G Benditt Ganesh Raveendran 2017World Journal of Cardiology2017,9,2:5
4Anti-inflammatory activity of the leaf extacts of Gendarussa vulgaris Nees显示文摘Objective:To evaluate the anti-inflammatory property of the leaf exacts of Gendarussa vulgaris(G.vulgarix) Nees.Methods:G.vulgarix Nees of the family Apocynaceae is a medium sized tree grown in semishade or no shade and is common in the Ernad and Nilambur taluks of Kerala. Various parts of this plant have been used in the treatment of ulcers,sores,inflammation, dyspepsia,healing of wounds,etc.The present study aimed at the evaluation of anti-inflammatory property of the aqueous and alcoholic extracts of the leaves by both in vitro and in vivo methods. In vitro method was estimated by human red blood cell membrane stabilisation(HRBC) method and in vivo method was estimated on the carrageenan induced paw oedima.Results:Both the methods showed significant anti-inflammatory property of the different extracts tested. Conclusions:The alcoholic extract at a concentration of 300 mg/mL showed potent activity on comparing with the standard drug diclofenac sodium.TK Mohamed Saleem AK Azeem C Dilip C Sankar NV Prasanth R Duraisami 2011Asian Pacific Journal of Tropical Biomedicine2011,1,2:3
5Adult duodenal intussusception associated with congenital malrotation显示文摘Enteroenteric intussusception is a condition in which full-thickness bowel wall becomes telescoped into the lumen of distal bowel. In adults, there is usually an abnormality acting as a lead point, usually a Meckels' diverticulum, a hamartoma or a tumour. Duodeno-duodenal intussusception is exceptionally rare because the retroperitoneal situation fixes the duodenal wall. The aim of this report is to describe the first published case of this condition. A patient with duodeno-duodenal intussusception secondary to an ampullary lesion is reported. A 66 year-old lady presented with intermittent abdominal pain, weight loss and anaemia. Ultrasound scanning showed dilated bile and pancreatic ducts. CT scanning revealed intussusception involving the full-thickness duodenal wall. The lead point was an ampullary villous adenoma. Congenital partial (type Ⅱ) malrotation was found at operation and this abnormality permitted excessive mobility of the duodenal wall such that intussusception was possible. This condition can be diagnosed using enhanced CT. Intussusception can be complicated by bowel obstruction, ischaemia or bleeding, and therefore the underlying cause should be treated as soon as possible.J Gardner-Thorpe RH Hardwick NR Carroll P Gibbs NV Jamieson RK Praseedom 2007World Journal of Gastroenterology2007,13,28:3

11胆汁淤积性瘙痒的原因显示文摘瘙痒是一种根痛苦的症状,常并发于肝胆疾患引起的肝胆淤积综合征。胆汁淤积性瘙痒对病人的生活质量可产生严重的不良影响。它不仅妨碍正常的活动,甚至引起失眠和自杀倾向。这种瘙痒是肝移植的一个指征。胃肠病学家面对这类问题常固缺乏台适的选择,无法使病人得到根本缓解而感到无能为力和丧失信心。以往采用的Heroin法(如血浆活性碳吸附再灌注,使部分胆汁体外分流)表明常规的抗瘙痒治疗通常是无效的。如果仍采取经验性处理的原则,而不是在明确致病机理的基础上得出正确理论,这种令人棘手的情况可能还不会在根本上得到解决。Jones EA Bergasa NV 邹明 1997现代消化病及内镜杂志1997,2,2:2
